(3x^4)-5=43<br><br>How?? <br><br>It's supposed to be - 2?​
Sergeeva-Olga [200]

Answer:

I got 2 as an answer

Step-by-step explanation:

( {3x}^{4} ) - 5 = 43 \\ ( {3x}^{4} ) = 43 + 5 \\ ( {3x}^{4} ) = 48 \\  \frac{ {3x}^{4} }{3}  =  \frac{48}{3}

{x}^{4}  = 16 \\  \sqrt[4]{ {x}^{4} }  =  \sqrt[4]{16}  \\ x = 2

Write an equation of the circle with center (-7, 4) and radius 8.
Stels [109]

answer

(x+7)^2 + (y-4)^2 = 64

set up equation

the equation of a circle is (x - h)^2 + (y - k)^2 = r^2

where h is the center x coordinate and k is the center y coordinate

values

from the point (-7,4) we know that h = -7 and k = 4

since the radius is 8, r^2 = 8^2 = 64

plug in values

now that we have all the values, we plug them into (x - h)^2 + (y - k)^2 = r^2

(x - h)^2 + (y - k)^2 = r^2

(x - (-7))^2 + (y-4)^2 = 64

(x+7)^2 + (y-4)^2 = 64

Lerok [7]
She spent $23.25, how I got my answer.

I divided $13.50÷2=$6.75 then I added $6.75+3=$9.75 then I added $9.75+$13.50=$23.25.

I hope this helps.

3x^2(x^3-1)+2x^3(2x^2+2) <br> Whats the simplified answer?
ahrayia [7]

Answer:

\large\boxed{7x^5+4x^3-3x^2}

Step-by-step explanation:

3x^2(x^3-1)+2x^3(2x^2+2)\qquad\text{use the distributive property:}\ a(b+c)=ab+ac\\\\=(3x^2)(x^3)+(3x^2)(-1)+(2x^3)(2x^2)+(2x^3)(2)\qquad\text{use}\ a^na^m=a^{n+m}\\\\=3x^{2+3}-3x^2+4x^{3+2}+4x^3\\\\=3x^5-3x^2+4x^5+4x^3\qquad\text{combine like terms}\\\\=(3x^5+4x^5)-3x^2+4x^3\\\\=7x^5+4x^3-3x^2
